the only thing i will suggest is this, the basic need is a welder and someone handy with a welder.
other than that:
1. you want to get the motor in as far back and as low as possible(to keep a reasonable chassis balance)
2. if you want to get the motor in as far back and as low as possible you'll need to mod the sump
3. use a R32 gearbox with a SR bellhousing/front case, it will stop you spending countless hours cutting up ur tunnel to fit the gearbox/shifter
4. your stock radiator dosn't stand a chance but the s13 one fits with minamal mods
5. brush up on wiring skills and how to read factory wiring diagrams or know someone who does.
the rest is basic fabrication and common sense
ohh and don't rant on about bashings of cross-breeding, and then bash on a CA.
